Build vascular access of arteriovenous fistula in line with hemodislysis needs. Vascular trill is palpable. Use blood pump to puncture arm model to simulate to build blood circulation access. Use puncture needle to separately puncture relative vascular to conduct vascular operation training.
1. Hemodialysis simulated arm
2. Squeezing balloon to simulate radial artery pulsation
3. After building up vascular access of arteriovenous fistula, vascular trill is palpable.
4. Simulate blood circulation access: connect hemodialysis arm with blood pump, fluid reservoir and two installations of puncture vascular.
